Intuitive file naming can only help to add pertinent search content to your site. Images with file names such as DSC001.jpg, DSC002.jpg miss a huge opportunity to present data to the search engines. Through your editSuite you have the ability to upload images with meta-data intact as well as add image titles, descriptions, and keywords through the 'edit' button found in the lightbox module, but this does not overwrite the actual name that you assigned to the file when it was created. For the absolute best results we recommend titling files according to their visual content or target keywords. For more information, the topic thread on Search Engine Optimization offers more advice and a link to a tutorial video.
